71 LT-1 intake manifold

[Peter Wilson]

I am presently running a bigblock in my 71 Z/28 ,but have recently acquired the original numbers matching shortblock for my car . I am going to try to assemble the shortblock with a good set of original heads ( when I find them ) . I have located an original Winters intake with the proper GM casting number and it also has a 600 double pump Holley on it . I asked the guy to sell it . he's had it for 25+ years and he is going to let me know this week if he will sell or not . Its kind of a keep sake for him as its off his old 71 Z ,but he also knows he will probably never ever use it . the intake should be cleaned and or beadblasted and visually it looks good , no noticeable cracks , does not appear to have been planed and there is no corrosion in the water jackets . The carb is not correct for my engine , but is still good for a future project after its rebuilt , or to sell or barter for something I need. what is this package worth ? I figured 50 for the carb and $150 to 200 for the intake . Is this a reasonable offer ? Is it worth more ? I dont want to pay too much and dont want to lowball the guy so he doesnt end up selling . any opinions will be appreciated , thanks

I posted a "what is it worth" thread on this site about two years ago asking what my '71 winters Z28 intake manifold was worth and sold it for $350 in two hours in hind site I probably could have gotten more.

Not sure how accurate you're trying to restore your car but just as an FYI, the 71 intake is different than the 1970. I believe the mounting for the thermostat choke coil is different and no oil filler tube hole for 71 (so no freeze plug). Mike

This intake is #3959594 , I had a hard time seeing the number because it was underneath the float bowl .the carb was bolted to the intake and I didnt have any tools with me to remove it . but I was able to get the number off it . I checked the number on the NastyZ specifications page and it shows for a 71/72 LT-1 . Its looking like the offer I was thinking of throwing at him would have been a little low . Thinking maybe I should offer a bit more if he does decide to sell . then I have to find some 487 heads in good shape .

That would be correct for your car. Your offer might be a little low but you can always go up. If your offer is too much you'll never know it. Don't let that one get away.

ask seller what he wants, go from there

No freeze plug on a '70 intake either. The choke mounting pedestal is indeed different. A '71/2 intake will have the cylinder numbers cast into each intake runner...a '70 will not.

Got it !

Got the intake and carb for $250 , casting # 3959594 . intake seems to be in good shape , I'll have to bead blast it for sure . no cracks , corrosion , etc. oil baffle / splash shield on bottom of intake is in good shape and not rusted or dented . the list # 4776-2 Holley needs a major rebuild , throttle shafts seized etc . thats no biggie though , I just wanted the intake !

I have a pair of 487 castings that are the 1.94 version so they are just mundane stock. Still covered in 40 years of grease and grime.


I wonder what my DZ intake and Carb are worth?.....
